A testable prediction is a...
What is a hypothesis?
Process plants use to make their own food
What is photosynthesis?
What do animals release when they breathe?
What is Carbon Dioxide?
This macromolecule is the body’s main source of quick energy and includes sugars and starches.
What are carbohydrates?
These cells do not have a nucleus and are usually smaller and simpler than other cells.
What are prokaryotic cells?
What is the first step of the scientific method? (not a hypothesis)
The natural home of an animal, plant, or other organism
What is a habitat?
Where do plants take nitrogen compounds in through?
Their roots.
These macromolecules are made of amino acids and are responsible for enzymes, structure, and transport in cells.
What are proteins?
This type of cell contains a nucleus and membrane-bound organelles.
What are eukaryotic cells?
This variable changes because the independent was manipulated...
What is the dependent variable?
How much percentage of energy is lost in each trophic level?
90%
What is the process that plants use when they release water vapor?
What is transpiration?
This macromolecule is composed of fatty acids and is used for long-term energy storage and insulation.
What are lipids?
This organelle is found in plant cells but not animal cells and is responsible for photosynthesis.
What is the chloroplast?
A factor that does not change through the whole experiment. It is not a control.
What is a constant?
Breaks down dead organisms and releases nutrients from the dead matter into the environment around them.
What is a decomposer?
What are the 4 main stages in the water cycle?
What is evaporation, condensation, precipitation, and run off?
Monosaccharides, amino acids, and nucleotides are examples of these smaller units that build macromolecules.
What are monomers?
These two structures are found in plant cells but not animal cells and help provide support and structure.
What are the cell wall and central vacuole?
On a graph, which axis would the independent and dependent variables be located?
X- Independent Y-dependent
A non-native organism introduced to a new ecosystem that spreads rapidly and causes harm to the environment
What is an invasive species?
What causes nitrogen fixation?
What are bacteria in the soil?
This macromolecule stores and transmits genetic information and includes DNA and RNA.
What are nucleic acids?
This cell membrane transport process moves molecules from an area of high concentration to low concentration and does not require energy.
What is diffusion?
